High-Density Seats and Seals: Designed to function in cryogenic service, with the valve rated for operation down to -196°C.
Vent Hole on the Upstream Face of the Ball: Prevents cold liquids from becoming trapped in the valve, ensuring smooth operation in low temperatures.
Blow-Out Proof Stem Design: The stem primary seal and bearing are located near the packing end of the extended stem, protecting them from cryogenic temperatures.
Special Cleaning and Packaging: Valves are specially cleaned to remove all grease and oils that may react with the service media. Each valve is packaged and sealed in a heavy poly bag to keep it clean until installation.
